INTEGERS: Definition: Positive and negative numbers. Positive numbers are greater than 0. Negative numbers are less than 0. Zero is not positive or negative.
Opposites: The positive and negative version of the same number. Example: +77 and -77 are opposites. Opposites always add to 0. Example: 62 + -62 = 0 In Real Life: Positive Examples: Getting paid Gaining anything Depositing $ Above sea level Negative Examples: Buying Losing anything Withdrawing $ Below sea level Absolute Value: Tells how many units an integer is from zero. Absolute value is always the positive version of the integer. Symbol: l l Example: l 13 l......Say, "The absolute value of 13 is 13." l -99 l......."The absolute value of negative 99 is 99." Comparing and Ordering: < Less than > Greater than = Equal to The further you go right or up from 0, the value increases The further you go left or down from 0, the value decreases Examples: -8 < - 6 because it is further left on a number line 8 > 6 because it is further right on a number line -57 > -101 l -28 l = 28
Order from least to greatest: -1001 < -9 < -5 < 7 < 50 Number Lines: Can be horizontal or vertical. Positive numbers are to the right of 0 or above 0. Negative numbers are to the left of 0 or below 0. Horizontal: Numbers increase in value as you move right. Numbers decrease in value as you move left. Vertical: Numbers increase in value as you move up. Numbers decrease in value as you move down,

In Real Life:
Positive Examples: Getting paid Gaining anything
Depositing $ Above sea level
Negative Examples: Buying Losing anything
Withdrawing $ Below sea level
Absolute Value: Tells how many units an integer is from zero. Absolute value is always the positive version of the integer.
Symbol: l l
Example: l 13 l......Say, "The absolute value of 13 is 13."
l -99 l......."The absolute value of negative 99 is 99."
Comparing and Ordering: < Less than > Greater than = Equal to
The further you go right or up from 0, the value increases
The further you go left or down from 0, the value decreases
Examples: -8 < - 6 because it is further left on a number line
8 > 6 because it is further right on a number line
-57 > -101
l -28 l = 28
Order from least to greatest: -1001 < -9 < -5 < 7 < 50
Number Lines: Can be horizontal or vertical. Positive numbers are to the right of 0 or above 0. Negative numbers are to the left of 0 or below 0.
Horizontal: Numbers increase in value as you move right. Numbers decrease in value as you move left.
